Mycoplasma is a/an__________organism.

Options

A. obligate anaerobe
B. facultative aerobe
C. obligate aerobe
D. facultative anaerobe

Answer

To answer the question "Mycoplasma is a/an__________organism," we will analyze the options provided and determine the correct classification of Mycoplasma.

### Step-by-Step Solution:

1. **Understand the Characteristics of Mycoplasma**:
- Mycoplasma are a unique group of bacteria that lack a cell wall. They are the smallest known free-living organisms and can survive without oxygen.

2. **Evaluate the Options**:
- **Option 1: Obligate Anaerobes**: These organisms cannot survive in the presence of oxygen. This is incorrect for Mycoplasma, as they can survive in oxygen-rich environments.
- **Option 2: Facultative Aerobes**: These organisms can survive with or without oxygen but prefer the presence of oxygen. This is also not entirely accurate for Mycoplasma.
- **Option 3: Obligate Aerobes**: These organisms require oxygen for survival. This is incorrect for Mycoplasma, as they do not strictly require oxygen.
- **Option 4: Facultative Anaerobes**: These organisms can grow in both the presence and absence of oxygen. This is the correct classification for Mycoplasma, as they can survive in varying oxygen conditions.

3. **Conclusion**:
- Based on the analysis of the options, Mycoplasma is best classified as a **Facultative Anaerobe**.

### Final Answer:
Mycoplasma is a **Facultative Anaerobe** organism.
